This critical component is part of the engine s fuel metering system, where its primary function is to atomize and precisely deliver fuel into the combustion chamber with exceptional efficiency and reliability. Constructed from high-grade materials, including a robust **hexagonal nozzle body** and a durable **ceramic or metal-oxide coating** on the internal passages, the 290 Hex Jet Nozzle ensures optimal fuel spray patterns, minimizing droplet size for improved combustion stability and reduced emissions. Its **290-degree spray angle** is meticulously calibrated to optimize fuel-air mixing, enhancing engine performance while maintaining operational efficiency across a wide range of power settings, from idle to full thrust. The nozzle s **AB290 designation** indicates a specific aerodynamic and thermal design tailored for high-pressure fuel systems, where resistance to coking, erosion, and thermal stress is paramount. Ideal for both military and commercial applications, this nozzle is engineered to withstand the extreme conditions of modern jet engines, including high-temperature environments and cyclic duty cycles, ensuring longevity and consistent performance. Whether integrated into a next-generation commercial airliner or a specialized military aircraft, the 134-8290 AB290 Hex Jet Nozzle exemplifies Honeywell s commitment to innovation in propulsion technology, delivering unmatched reliability and fuel efficiency in the most demanding aviation environments.

### **Pros and Cons of Buying a 1982-1990 Abarth 290 Hex Jet (NOS Never Opened Stock)**

#### **Pros**

1. **Iconic Italian Design and Performance**

The Abarth 290 Hex Jet is a legendary front-engine, rear-wheel-drive sports car built on a Fiat 131 chassis. It features a 2.9L inline-six engine (derived from the Fiat 131 Abarth) producing around **170 180 horsepower**, which was impressive for its time. The car s aggressive styling, pop-up headlights, and racing pedigree make it a sought-after collector s item.

2. **Strong Engine and Drivetrain**

The engine is a robust, naturally aspirated inline-six with a single Weber carburetor (later models had fuel injection). It is known for reliability if maintained properly. The manual transmission (five-speed in later models) is smooth and engaging, offering a classic driving experience.

3. **Low Mileage and NOS Condition**

A never-opened stock (NOS) example means the car has never been driven, which is extremely rare and highly desirable. The engine, transmission, and interior remain in original, pristine condition, preserving its value and historical integrity.

4. **Collectible Status and Investment Potential**

Abarth 290 Hex Jets are part of a small production run (around **1,000 1,500 units** were made between 1982 1990). Their scarcity, combined with their racing heritage (including Group 4 rally and endurance racing), makes them valuable to enthusiasts and collectors. Prices have been rising steadily, especially for well-preserved examples.

5. **Rally and Racing Heritage**

The 290 Hex Jet was a homologation special for rally racing, meaning it was built to compete in international motorsports. This adds to its prestige and appeal among performance car collectors.

6. **Classic Italian Craftsmanship**

The car features hand-built components, including the body (made by Pininfarina), interior, and mechanicals. The attention to detail in its construction makes it a standout example of Italian automotive design from the 1980s.

7. **Potential for Restoration (If Needed)**

While this is a NOS car, if future owners choose to modify it (e.g., upgrading the engine, suspension, or interior), there is room for customization without losing its core identity.

---

#### **Cons**

1. **Extremely High Purchase Price**

A NOS 290 Hex Jet is not an affordable car. Prices for well-documented, original examples can range from **$150,000 to over $300,000 **, depending on condition, provenance, and rarity. This makes it a significant financial commitment, even for serious collectors.

2. **Limited Availability and Competition**

Due to its rarity, finding a genuine NOS example is difficult. Many potential buyers may end up competing with other collectors in auctions (e.g., RM Sotheby s, Bonhams), driving prices even higher.

3. **Maintenance and Preservation Costs**

Even in NOS condition, the car will require occasional maintenance to keep it running perfectly. Parts for a 40-year-old Italian sports car can be expensive, and some components (e.g., original Weber carburetors, clutch, or suspension parts) may need replacement over time. Storage (e.g., climate-controlled garage) is also a consideration to prevent deterioration.

4. **Driving Experience Limitations**

While the car is fun to drive, it is not a daily driver. The manual transmission, basic interior, and lack of modern safety features (e.g., ABS, airbags) make it impractical for everyday use. Fuel economy is poor ( 12 15 MPG), and the ride can be stiff compared to modern standards.

5. **Potential for Forgery or Misrepresentation**

Due to its value, there is a risk of counterfeit or altered examples being sold as NOS. Buyers must thoroughly document the car s history, including original paperwork, build records, and chassis number verification. Reputable sellers (e.g., auction houses, trusted dealers) are essential to avoid scams.

6. **Insurance and Legal Considerations**

Insuring a high-value classic car can be costly, especially for a rare model like the 290 Hex Jet. Additionally, some regions have strict regulations on historic vehicles, which may require additional paperwork or modifications to comply with modern standards.

7. **Depreciation Risk (If Not a Collector s Item)**

While the 290 Hex Jet is appreciating in value, this is not guaranteed for all classic cars. If the buyer is not a serious collector or does not plan to preserve the car long-term, they may face depreciation risks similar to any high-end collectible.

---

### **Conclusion**

The **1982 1990 Abarth 290 Hex Jet (NOS)** is one of the most desirable Italian sports cars from the 1980s, offering a unique blend of racing heritage, iconic design, and mechanical excellence. Its rarity, historical significance, and growing collector demand make it a strong investment for those who appreciate classic automobiles. However, the **extremely high purchase price, maintenance costs, and impracticality as a daily driver** must be carefully considered.

For the right buyer a passionate collector with deep pockets and a commitment to preservation the 290 Hex Jet is an extraordinary acquisition. For others, the financial and practical burdens may outweigh the enjoyment.

---

### **Final Recommendation**

- You are a serious collector with a budget to match (expect to spend **$200,000 ** for a top-tier example).

- You value the car s **racing history, Italian craftsmanship, and rarity** over modern convenience.

- You have access to **proper storage, maintenance expertise, and insurance** for a high-value classic.

- You plan to **preserve it in original condition** or restore it with period-correct parts.

- You need a **daily driver** or a practical vehicle.

- You cannot afford the **ongoing costs** of ownership, including maintenance, insurance, and storage.

- You are unsure about the car s **authenticity** and cannot verify its NOS status thoroughly.

- You do not have a **long-term plan** for the car s preservation or potential resale.

For most buyers, this car is a **once-in-a-lifetime purchase** one that should be made with careful consideration and a deep appreciation for automotive history. If you meet the criteria, it will be an unforgettable addition to any collection. If not, there are many other classic sports cars that offer similar thrills at a more accessible price.
